The SRFI says:

The latter part is non-portable, since neither R6 nor R7 define
procedure properties.  Do suite loaders really need to be disjoint from
other procedures?  I can't see a compelling reason.

If there *is* a good reason (and there may be--I just woke up), then
I'd prefer the usual solution: make suite loaders "objects of a
disjoint type" and provide a simple 'suite-loader-load' procedure.
